Thoughts on silicone in handle bars and in frame of bike to reduce vibration...

[cabinfever1977]

I have a custom front mount and use rubber handlebar grips cut in half between my mounts and frame.
My mounts are tight and bolts are double nutted plus i have a muffler strap to hold muffler and engine to frame.
i never have to straighten or alighn nothing.

Vibration

I used 3/4 by 3" bolts screwed into the handle bar to create bar end weights.
kills 90% of bar vib's. They made generic bar end weights in the past but i couldn't find any. So....

what about silicon on the motor mounts... or silicon and rubber =-)

If anyone has vibration that bad, the engine is not mounted to the frame correctly. My first build with engine #1 vibrated so bad that my hands tingled for 30 minutes after riding. I took that SAME engine and mounted it on another frame (first one cracked in two...cause....drillinbg a hole in the tube), mounted engine to frame, not frame to engine and can ride for hours without undue vibration. Find the cause, fix it, don't try to hide it. Three other builds with same type engine and no vibration problems. Proper mounting is the #1 key for the smoothest ride. Number 2 is true running wheels and tires. I NEVER start a build that I don't first true up the wheels. This should be done before the engine is ever taken out of the box. I don't care if the bike is new or used.

I have a terrific answer to the question posed in the thread but it would only get me banned

Well then, by all means, let's hear your answer.

Zev- that was a good one. But I like Fabian, am curious though.
I'm with Al on this one, the handlebars are just ringing in sympathy with the engine vibes.

Surely now, you wouldn't want to see me banned
I need to invest time in a suitable protege before getting booted

When I had my engine, it vibrated like crazy. I almost had to wear a diaper... After some chatter on the web, I found that it was very possible I had a bad crank. So I tore it apart only to find I had the Devil's Engine! Half the stuff wouldnt come apart and I found that the crank spun like a banana. The large flat head screw on the crank gear spun in a cone shape. LOL. So I sold it a few months ago and the last ~4 months have been very, well, flat. Right now, Rich is bulding me a hand made engine with ported cylinder and those nice bearings. Can't wait to get it. I told you that to tell yall this. These engines are like snowflakes, not one is the same as another. The first one may be less "balanced" than the other. When you have multiple MBs, one fix might not work on all the bikes. Keep that in mind when diagnosing these bikes. "This one doesnt run the same as my last one" Well, if it did, then that would be a miracle. LOL
